Surdition, the less pronounced bulge of the roof sheet y is easier to fabricate than some of the more ex'-4 treme forms of protuberances.

According to the present invention, the adjacent marginal portions 2| of therespective sheets are connected together by a special joint running the width of the roof as will be described in its various modifications.

Referring to Figure 3, this joint includes a clip B made of ungalvanized .metaland having a dome 95 adapted to receive upturned ends 2| of the roof sheets, which are juxtaposed as indicated. A weld 91 joins the ends 2| of the sheets and the member 85 together. Seam welds 92 also join the upper and lower reinforcing members to Y each other and to the marginal portions of the portions and 3| overlying and underlying theedge of the sheet respectively, and a sloping portion 32 disposed towards the adjacent clip. The joint is completed by a fillet weld 35 which is laid in' the V formed between the two clips. Arseam weld'fV extends through the portions 30 and 3| and the marginal portion 2| of each sheet. Thus each clip runs the entire width of the sheet and is' securely 'fastened to theV marginal portions thereof. Theclips are securely fastened toone another,'completingthe joint;

Figure 4 illustrates another'form'of joint in which a clip Cisemployed. This clip is different in "construction totheclip Bin that the upper portion't'has the conformation indicated so that theedge of the clip has a vertical face 41 which is juxtaposed to a 'similar'fac'e on the ad-v jacent clip and a diagonalfface'48; A V-shaped channel is formed betweentheface'slof the respective clips.` `A fillet weld 45'is`laid in the channel.V Similarly to 'the joint illustrated in Figure 3 a seam weld4'6 secures the upper and lower portions of Vthe clip and themarginalportion 2| of the sheet togethenj f j Figure 5 illustrates another'fornr of joint in which a substantially L-shaped clip is employed having upper and lower portions 5U Vand 4|,

adapted respectively to 'overlie andunderlie the 45 marginal portion'2l ofits sheet." The .clip is provided withjan upstandingV portion 51'ada1'itedV to 'abut the similar portion 'of the adjacentfclip and having a diagonal edge' 52 adapted toform with a similar edge on the adjacent clip 'a chan'- 50 neltoreceive a llet weld 55. 'A seam weld 56 joins the upper portion 5|) and 5| to'themarginal portion'Z'l of the sheet. 1

Figure 6 illustrates still another form of `joint inwhich the marginal portions are held together 55 Figure'lillustrates another form of joint which theedges2|10ftheroof sheets are bent over and hooked together 'as'indicated The' upper .reinforcing member 1,0 is 'domedias at'15 so as tohouse the joined ends of the slieets2ll' roof sheets.

As shown in Figure 2 a running board |6 may a be secured to the joint by-angle irons saddle |1 which are butted into the weld |5.

Advantages Various advantages of the invention will become evidenty from a study of the above description. Principal among these are the provision of strong, attractive joints which can be formed by welding without disintegration of the galvanizing ofthe roof sheets at unprotected points.

It `will be understood that, without departing from the' spirit of the invention or the scope of the claims, various modifications may be made in the specific expedients described. The latter are illustrative only and not offered in a restricting sense, it being desired that only'such limitations shall be placed thereon as may be required by the state of the prior art.
